Abstract

The invention relates to a pen prevented from being opened by a child, and the pen comprises a penholder, a pen cap and a refill. The refill is arranged in the penholder, protrusions are arranged on the inner circle of an opening of the pen cap, flanges are arranged at the pen point end of the penholder and matched with the protrusions, a pressure rod is arranged in the pen cap and can press the refill out of the penholder, first threads are arranged below the protrusions, and second threads are arranged at the upper end of the outer side wall of the penholder and matched with the first threads. The child can be prevented from opening the pen cap or pressing the refill out, and therefore safety is high.

Description

Prevent the pen of child

Technical field

The present invention relates to prevent the pen of child.

Background technology

Pen, is the mankind's a invention greatly, is for the instrument of writing or painting.In the family that has child, after adult uses pen, tend in the place that uses pen, pen be left over, child often can take up one's pen when toy use.General pen, child is easy to press out pen core or opens the pen cap, and child holds Pen Association's coating and drawing at random, made dirty clothes or furniture, and nib is sharper, draws on furniture and can on furniture, mark one trace, damage furniture, stamp, to eyes, accidentally just can injure eyes, very dangerous.

Summary of the invention

The present invention is directed to prior art deficiency, provide one can prevent that children from opening the cap for brush or pressing out pen core, safe pen.

In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: the pen that prevents child, comprise penholder, the pen cap and pen core, described pen core is arranged in described penholder, described pen cap opening part inner ring is provided with projection, described penholder pen tip is provided with the flange matching with described projection, in the described pen cap, be provided with the depression bar that pen core can be extruded to penholder, described projection below is provided with first screw thread, at described penholder lateral wall upper end, is provided with the second screw thread matching with described first screw thread.When needs are used pen, first the pen cap is extracted from pen tip, then, be enclosed within the upper end of penholder, in the process of cover, the second threaded engagement on first screw thread and penholder lateral wall in the pen cap is threaded, simultaneously, depression bar in the pen cap withstands pen core and presses down past pen core, pen core extrudes penholder the most at last, meanwhile, can rely on the degree of depth being threaded to decide and pen core need to be ejected to the length outside penholder, after finishing using, the pen cap is restored.

In technique scheme, in described penholder, be provided with fixed head and portable plate, described fixed head is fixed on described penholder inwall, between described fixed head and described portable plate, by elastic parts, be connected, on described fixed head, offer the through hole matching with described pen core, end, described pen core upper end is fixedly connected with described portable plate.Depression bar is depressed portable plate, makes the pen tip of pen core be forced out penholder, and meanwhile, elastic parts shrinks, after finishing using, the pen cap is separation with penholder, affected by elastic parts, and pen core is automatically withdrawn in penholder, easy to use.

In technique scheme, on described penholder inwall, offer the chute matching with described portable plate, described portable plate is arranged in described chute.Portable plate is moved up and down in chute, the slip of portable propelling plate, the moving range of restriction portable plate, prevents that portable plate from rising too high under the elastic force impact of elastic parts, recovered slow.

The present invention compared with prior art, has following beneficial effect: the present invention can prevent that children from opening the cap for brush or pressing out pen core, safe.Depression bar is depressed portable plate, makes the pen tip of pen core be forced out penholder, and meanwhile, elastic parts shrinks, after finishing using, the pen cap is separation with penholder, affected by elastic parts, and pen core is automatically withdrawn in penholder, easy to use.Portable plate moves up and down in chute, the slip of portable propelling plate, and the moving range of restriction portable plate, prevents that portable plate from rising too high under the elastic force impact of elastic parts, recovered slow.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present invention.

Fig. 2 is chute of the present invention and portable plate connection diagram.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: referring to Fig. 1 and Fig. 2, prevent the pen of child, comprise penholder 1, the pen cap 2 and pen core 3, described pen core 3 is arranged in described penholder 1, the described pen cap 2 opening part inner rings are provided with projection 21, described penholder 1 pen tip is provided with the flange 11 matching with described projection 21, in the described pen cap 2, be provided with the depression bar 22 that pen core 3 can be extruded to penholder, described projection 21 belows are provided with first screw thread 4, at described penholder 1 lateral wall upper end, be provided with the second screw thread 5 matching with described first screw thread 4.

In described penholder 1, be provided with fixed head 12 and portable plate 13, described fixed head 12 is fixed on described penholder 1 inwall, between described fixed head 12 and described portable plate 13, by elastic parts 14, be connected, on described fixed head 12, offer the through hole matching with described pen core 3, described pen core 3 ends, upper end are fixedly connected with described portable plate 13.Depression bar 22 is depressed portable plate 13, makes the pen tip of pen core 3 be forced out penholder 1, and meanwhile, elastic parts 14 shrinks, after finishing using, the pen cap 2 is separation with penholder 1, affected by elastic parts 14, and pen core 3 is automatically withdrawn in penholder 1, easy to use.

On described penholder 1 inwall, offer the chute 6 matching with described portable plate 13, described portable plate 13 is arranged in described chute 6.Portable plate 13 is moved up and down in chute 6, the slip of portable propelling plate 13, the moving range of restriction portable plate 13, prevents that portable plate 13 from rising too high under the elastic force impact of elastic parts 14, recovered slow.

When needs are used pen, first the pen cap 2 is extracted from pen tip, then, be enclosed within the upper end of penholder 1, in the process of cover, second screw thread 5 cooperations on first screw thread 4 in the pen cap 2 and penholder 1 lateral wall are threaded, simultaneously, depression bar 22 in the pen cap 2 withstands portable plate 13 portable plate 13 is subdued, elastic parts 14 shrinks thereupon, and pen core 3 moves down simultaneously, pen core 3 extrudes penholder 1 the most at last, simultaneously, can rely on the degree of depth being threaded to decide and pen core 3 need to be ejected to the length outside penholder, what be namely threaded is darker, it is also just larger that pen core 3 stretches out length outside penholder 1, can easily control pen core 3 and stretch out the length outside penholder 1.After finishing using, the pen cap 2 is restored to the pen tip that is enclosed within penholder 1.Even if child extracts the pen cap, pen core can not be pressed out, thereby prevent the damage that child uses pen core to cause clothes, furniture, or the body part such as eyes to child causes damage.
